JOINT FOR THE BRICKS OF LADLE- RODS.

SPECIFICATION forming part of Letters Patent No. 349,265, datedSeptember 14, 1886.

To all whom it may-concern.-

Be it known that we, MORGAN VILLIAMS and SAMUEL WINFIELD VAUGHEN,citizen of the United States, residing at J ohnstown, in the county ofCambria and State of Pennsylvania, have invented certain new and usefulImprovements in Joints for Covering Bricks of Ladle-Rods; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is arepresentation of this invention, and isavertical section. Fig. 2 is a plan view of the convex end of the brick.Fig. 3 is a plan view of the concave end of the brick. Fig. 4 is adetail view.

Our invention relates to joints for the sleeve or covering-brick for theiron rod used in stopping the pouring opening in ladles for molten steelor iron; and it consists in the construction of parts, as hereinafterdescribed, and pointed out in the claim.

In this class of j oints as heretofore construct ed there has beenconsiderable trouble experienced from the fact that, owing to theirshape, the molten steel or iron will get through to the rod, therebyburning it, and causing great expense and trouble as well as delay inrepairing and replacing the rods.

The object of our invention is to obviate these defects by constructingthe joints of the bricks, so that they will hold the mixture used forbinding or cementing the joint in place, and will present so muchsurface to the molten steel or iron that may enter the joint that saidmolten steel or iron will solidify before it can pass all of theobstructions placed in its course, and will therefore do no harm to therod.

Referring by letter 'to the accompanying drawings, A designates onesection of the sleeve or covering-brick, which is provided at one endwith an annular shoulder, B, from which rises an integral convex bead,O, and from this Serial No. 208,509. (No model.)

bead C rises or extends an integral ring or bead, D, which is convex onits outer face, which terminates in a plain integral inwardlyprojectingshoulder, E, which terminates at the axialbore F of the brick, theshoulder B and beads C and D forming the male portion of the joint whentwo sleeves or bricks are united on the rod. At its opposite end thesection A is provided with an interior shoulder, G, which is designed toabut against the interior shoul der, E, of an adjoining section ofsleeve, and surrounding this shoulder G is an annular groove, H, for thereception of the bead or ring D of the next sleeve, and next to this,nearer the end of the sleeve or brick A, is a concave portion, I, whichis designed to receive the integral ring or bead, D, of an adjoiningsection of sleeve, the outer face or end of the sleeve or brick at Itbeing plain or bounded by the straight line, which permits this portionk to match or meet the shoulder B of the next section of sleeve, thecement used at the joint, however, intervening to render the jointpractically tight, to prevent the influx of the molt-- en steel or iron.The ladle-rod passes through the axial bores of the sleeves, and is bythem protected from the molten steel or iron, as the case may be.

Having described this invention, what we claim, and desire to secure byLetters Patent, 1s

A sleeve or brick section for ladle-rods, said sleeve being provided onone end with the male portion of a joint, comprising the shoulder B, theconvex bead C, the ring or bead D, and the shoulder E, and provided 011the other prising the shoulder G, the groove H, the concave portion I,and the plain portion K, substantially as specified.

In testimony whereof we afiix our signatures in presence of twowitnesses.
